F+, LARGE SPECIMEN - GOOD TO COMPARE WITH BRAZILIAN SPECIMENS. THE DIFFERENCES BETWEEN ORNATA AND SENTIS ARE MAINLY ON THE RIBS, BUT I ADMIT IT IS NOT SO CLEAR... COLLECTED BY HOMER RHODE IN BERRY ISLANDS

F++, LARGE! ONE OF THE RAREST PECTINIDAE! WRONGLY CONSIDER AS SYNONYM OF C.TEHUELCHUS - THE SEHLL HAS TOO MANY DIFFERENCES AND IS GEOGRAPHIC RESTRICTED WITHOUT "HYBRIDS"! ENOUGH TO BE A FULL VALID SPECIES!
